Image Optimization 5-27
5.7.2 Parameters
Parameter Area Display
When entering the imaging mode, the screen displays the contrast image. If the [Dual Live] is
“ON”, both the contrast image (marked with “ ”) and tissue image (marked with “ ”) are
displayed (the two window positions can be changed). Parameter area displays as follows:
Type Parameter Meaning

FC H Contrast frequency
D Depth
G Gain

Image Optimization
The parameters in Contrast mode are similar to those in B mode. See B mode imaging parameters
for details. Special imaging parameters are introduced below.
Timer
The two timers are used to record the total time of the contrast imaging and the single time of one
contrast exam.
After the image is frozen, Timer 1 is still running, and after unfreezing, the corresponding time can
be seen.
Timer 2 stops timing when an exam is frozen, and after unfreezing, Timer 2 is off.
NOTE: The starting time displayed may be inconsistent with the actual one due to system
error or some other human error. Check the agent-injecting time.
Activate [Timer 1(2)] to start timing from the moment you inject the contrast agent. The screen
displays the times in the bottom-right corner.
 The time begins at 0.
 In live mode, the elapsed time is displayed. For example, 00:00:08 means the elapsed time is
8 seconds.
 If the image is frozen during timing, the timer stops working and the elapsed time is displayed.
 Turn off [Timer 1] or [Timer 2] and the timer stops running.
Micro-bubble Destruction
Function: to destroy the micro-bubbles left by the previous contrast imaging, or observe the
reinfusion effect in a continuous agent injecting process.
 Entering: tap [Destruct] to enable the micro-bubble destruction function.
 Parameters: set the parameters using the menu controls.

[DestructAP(dB)]: adjust the destruct acoustic power.

[Des.Time(ms)]: adjust the destruct time.
